Comparison of corrected and rescaled surface water concentrations of microplastics in SFB collected using manta trawl with food-dilution threshold derived by Mehinto et al. [42]. A percentages of samples exceeding each threshold are shown as bar plots, with solid-line error bars reflecting the 25th and 75th percentiles and dashed-line error bars reflecting the 95th percentile confidence intervals derived using Monte Carlo simulations (n = 10,000) based on probability density functions derived from the combined variability of correction factors and rescaling. B Empirical cumulative density plot of surface water concentrations and 25th and 95th percentile confidence intervals of correction factors compared to food dilution thresholds. Exceedances are only considered statistically significant when the 95% confidence interval does not include ‘0%’
